It's been a month, and I have been driving online taxi. And since then, I have realised why they all talk about having a dash cam or smart glasses. So, if there is a valid reason, such as this go for it. Other than that, not at all. Everyone deserves a respectful privacy. I still have to think whether to purchase one or not, as I do not want to interfere. But the police is corrupted here, so for their heinous activities, I will go for it.

Btw, smart people do not buy smart glasses. Blind people might have a better reason to :)
